摘　　要：Al_(2)O_(3)作为一种重要的载体在催化领域有着广泛应用,它是一种形态变化复杂的两性化合物,已知有9种晶型,不同晶型的Al_(2)O_(3),即便是同一种晶型Al_(2)O_(3),它的宏观及微观结构性质因制备方法不同有很大差异,进而影响乃至决定催化剂的性能。综述了近年来Al_(2)O_(3)载体的研究进展,介绍了Al_(2)O_(3)的织构、结构和表面特性,重点探讨了载体物性与催化性能间的构效关系,并提出了Al_(2)O_(3)载体未来研究工作的发展方向及研究重点。As an important support,Al_(2)O_(3) is widely used in the field of catalysis.It is a kind of amphoteric compound with different morphologies.So far it is known that it has 9 crystal forms.The macro and microstructure properties of different kinds of Al_(2)O_(3),whether they have the same crystal form or not,can vary greatly according to their preparation methods,which in turn affect and even determine the performance of the catalyst.This paper summarizes the research progress of Al_(2)O_(3) support in recent years,introduces the texture,structure and surface characteristics of Al_(2)O_(3),and focuses on exploring the structure-activity relationship between physical properties of the support and the catalytic properties.The development direction and keys of future research on Al_(2)O_(3) support are also put forward.
